It was noon before all uncertainly touching the character of the stranger ceased. By that time, however, both vessels were entering the Mona Passage; the brig well to windward, on the Porto Rico side; while the ship was so far to leeward as to be compelled to keep everything close-hauled, in order to weather the island. The hull of the last could now be seen, and no doubt was entertained about her being a cruiser, and one of some size, too. Spike thought she was a frigate; but Mulford still inclined to the opinion that she was one of the new ships; perhaps a real corvette, or with a light spar-deck over her batteries. Two or three of the new vessels were known to be thus fitted, and this might be one. At length all doubt on the subject ceased, the stranger setting an American ensign, and getting so near as to make it apparent that she had but a single line of guns. Still she was a large ship, and the manner that she ploughed through the brine, close-hauled as she was, extorted admiration even from Spike. “We had better begin to shorten sail, Mr. Mulford,” the captain at length most reluctantly remarked. “We might give the chap the slip, perhaps, by keeping close in under Porto Rico, but he would give us a long chase, and might drive us away to windward, when I wish to keep off between Cuba and Jamaica. He's a traveller; look, how he stands up to it under that could of canvas!” Mulford was slow to commence on the studding-sails, and the cruiser was getting nearer and nearer. At length a gun was fired, and a heavy shot fell about two hundred yards short of the brig, and a little out of line with her. On this hint, Spike turned the hands up, and began to shorten sail. In ten minutes the Swash was under her topsail, mainsail and jib, with her light sails hanging in the gear, and all the steering canvas in. In ten minutes more the cruiser was so near as to admit of the faces of the three or four men whose heads were above the hammock-cloths being visible, when she too began to fold her wings. In went her royals, topgallant-sails, and various kites, as it might be by some common muscular agency; and up went her courses. Everything was done at once. By this time she was crossing the brig's wake, looking exceedingly beautiful, with her topsails lifting, her light sails blowing out, and even her heavy courses fluttering in the breeze. There flew the glorious stars and stripes also; of brief existence, but full of recollections! The moment she had room, her helm went up, her bows fell off, and down she came, on the weather quarter of the Swash, so near as to render a trumpet nearly useless.
